A question about Kernel panic

[djman]

Hi!

I'm so sorry because I'm not good at English, so it will be a little difficult to read .

I have a board of samsung4412, when I boot the kernel, it will show "<0>Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b"

My kernel version is 3.5.0, here are some start information
$this->bbcode_second_pass_code('', '<5>Linux version 3.5.0-rc6-g115bae7-dirty (root@lenovo) (gcc version 4.6.x-google 20120106 (prerelease) (GCC) ) #9 SMP PREEMPT Mon Apr 21 15:50:49 CST 2014
CPU: ARMv7 Processor [413fc090] revision 0 (ARMv7), cr=10c5387d
CPU: PIPT / VIPT nonaliasing data cache, VIPT aliasing instruction cache
Machine: SMDK4412
')

And it show a Oops, too:

wm8994 1-001a: Failed to read ID register
<1>Unable to handle kernel NULL pointer dereference at virtual address 00000508
<1>pgd = c0004000

Control: 10c5387d Table: 4000404a DAC: 00000015

And I find some other problems:

My board have 2G RAM, and the uboot already read 2G RAM, but the kernel only read 728MB:
$this->bbcode_second_pass_code('', '<6>Memory: 384MB 344MB = 728MB total
<5>Memory: 713188k/713188k available, 65052k reserved, 0K highmem')

I try my best but it still no work

Can anyone could help me with this question?

Thank you!

Please supply a complete kernel panic, and preferably, boot log, so that we can actually see what happened.

An OOPS can sometimes be ignored as it will plow through. You're not specifying any location for a root filesystem, which is what is ultimately stopping the boot.
$this->bbcode_second_pass_code('', '<0>Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b')

[djman]

Hi kmihelich,

I think the boot stop at
$this->bbcode_second_pass_code('', '<1>Unable to handle kernel NULL pointer dereference at virtual address 00000508')

The boot information show:
$this->bbcode_second_pass_code('', 'PC is at mfd_remove_devices_fn+0x28/0x48
LR is at device_for_each_child+0x58/0x84')

So when the kernel call the mfd_remove_devices_fn, the panic happen.

I use objdump the dump the vmlinux, and I find where the mfd_remove_devices_fn is:
$this->bbcode_second_pass_code('', ' c0281300 <mfd_remove_devices_fn>:
c0281300: e1a0c00d mov ip, sp
c0281304: e92dd800 push {fp, ip, lr, pc}
c0281308: e24cb004 sub fp, ip, #4
c028130c: e92d4000 push {lr}
c0281310: ebf6353d bl c000e80c <__gnu_mcount_nc>
c0281314: e1a03000 mov r3, r0
c0281318: e5912000 ldr r2, [r1]
c028131c: e2400008 sub r0, r0, #8
c0281320: e59331c4 ldr r3, [r3, #452] ; 0x1c4
c0281324: e3520000 cmp r2, #0
[color=#FF0000]c0281328: e5933008 ldr r3, [r3, #8][/color]
c028132c: 0a000001 beq c0281338 <mfd_remove_devices_fn+0x38>
c0281330: e1520003 cmp r2, r3
c0281334: 9a000000 bls c028133c <mfd_remove_devices_fn+0x3c>
c0281338: e5813000 str r3, [r1]
c028133c: ebff96b1 bl c0266e08 <platform_device_unregister>
c0281340: e3a00000 mov r0, #0
c0281344: e89da800 ldm sp, {fp, sp, pc}
')

The red line is what the kernel do for the r3.

Now the value of r3 is 00000508, and the kernel can't handle the null poniter, I think the error is here.

It's the first for me to do the system migration, I still need to learn a lot of things.

Sorry for my poor English.

Given that it's getting to looking for a root filesystem that hasn't been specified, you should troubleshoot that first as it's the easiest. It has nothing to boot into, so it's not going to boot, and the kernel is going to panic every time because of that. The panic isn't in the oops, it's from not finding a root filesystem.

[djman]

Thank you, kmihelich

I never thought that the problem is from the root filesystem! I try to find the error from the kernel for two days...

The I use the ramdisk for my filesystem, but I don't make the filesystem by myself, I use others. And the name of the filesystem is "ramdisk-uboot", I check some datum, and I konw the ramdisk-uboot is make by mkimage tool.

It looks like I have to take a long time to make the filesystem.

Thank you for your answer!

[kmihelich]

I don't see it jumping into an initramfs, or its failing trying to somewhere in there. You could just grab one of our armv7 root filesystems and extract that onto whatever media you have access to from the board, then point it to that partition via a 'root=/dev/whatever' in your bootargs from U-Boot. Easy way to see if the kernel oops is really what is causing it to crap out, or if it will boot into something.

Booting into Arch (which uses systemd), you want to ensure your kernel is configured with the needed options:
http://cgit.freedesktop.org/systemd/sys ... README#n39

If it's not, systemd might crap itself, but if you get that far you at least know that's the issue and not the MFD driver that's causing the problem.

[djman]

Thank you for your suggestion, kmihelich, I will try my best to let the kernel start

If I have some problem in the debug, can I send a message to you?

[kmihelich]

You can post here, we'll all see it.
